rlhis invention relates to a connection for operatively attaching a power operated appliance to an automotive vehicle and is more particularly adapted for use with portable power operated appliances which are adapt'- ed to be moved from place to place with the automotive vehicle. Y This application is a division of our copending application, Serial No. 703,098, filed .Marchlsh 1924.

An important object ot this invention is the provision of means whereby a portable power .driven appliance may be securely attached to an automotive Vehicle and operatively `connected to the engine of such Vehicle. I

Al further vobject ot' this invention is the provision of a connection for operatively attaching `apower operated appliance to an automotive vehicle having apair of frame members and an engine,4 said connection including means for rigidly attaching the appliance to the frame members and a projecting shaft on the appliance formaking a power connection with the engine when desired. y

The invention will be described with particular reference to a portable air compressor, similar to that disclosed 'and claimed in the cofpending application aforesaid, but it is understood that the invention is not limited to such appliance and embodiment. i

In the accompanying drawings there is illustrated certain preferred embodiments of our` invention.

Figure l is a top plan View showing the appliance attached to an automobile.

Figure 2 is an enlarged sectional view showing the powerv connection to the appliance.

Figure 3 is a side elevation of a portion of the automobile trame with an attachment member in place.

Figure 4 is a sectional View on the line lV-flV of Figure 8, and

Figure 5 is a view similar to Figure 3 but illustrating a modied form of` the attachment member.

Referring to Figure l there is shown an air compressor 2 connected to an automobile indicated generally at 3, by meansof "attachment members 4 secured tothe automobile frame-by suit-able'bolts 6L Inthis embodiment the compressor 2 isfprovided with an attachment plate 7 which is bolted to the attachment members 4 by suitable nuts 8 engaging athreaded portion 9 extending k:from the forward end of the attachment member 4.

As shown in Figure 3 the attachment member 4l is VVprovided with a collar l0 against which Vthe attachment plate 7 is bolted. It will. be noted that the collar l() abuts the end of the fra-me 5; and acts as a spacer to hold the attachment plate in denite spaced relationship with the framewi- The frame 5 may be oftheA usual channely section (Fig. 4)\. The attachmentmember is shaped to fit snugly Qwithin the channel h and closely engage the walls thereof. Y It will thus be seen that the attachment members 4 forma rigid extension of the frame 5.- The bolts 6V extend'V through the web Vand flanges of 'the' channel section and thereby i insure; riofidity in all directions, adjacent boltspre erablyflyingat a substantial angleV to one another. i

In Figure 2 l there isfshown anengine in`' dicated generallyV by the lnumeral ll having ff a shaft extension 12' which is commonly provided for crankingthe engine. 'On account of .the possibility `of misalignment -due not only to small variations in dimensions of` either the vehicle or thel compressor, but

, also .diie vto the warpingfot the vehicle frame .when the vehicle is standing on uneven ground, it is desirable to 'provide a flexible ,connect-ion between the shaft l2 and the f shaft of the p ower operated appliance, in

this case, theair compressor. A connection ot this type isJ iilustre-.tred` generally by the 'numeral 1B. This connection is described in detail 1in our co-pending application,

.Serfin Nogmaoasana Win not be described herein.

It is obvious that any fiexible connection Whichwill transmit power between Y two shafts which are slightlyout ofalignment may be used. It is further desirable that the connection should afford means `whereby the power operated appliance may be disconnected from the motor when it is not desired tooperate theappliance.

Y It is frequent-ly desirable toleave the compresser in place while the vehicle is being moved from one object to another and, if desired, the disk 2O may be made slidable on the shaft 14 and provided with a springpressed pin 22 for holding it in or out of engagement with coacting parts of the disk on shaft 12. It will be understood that the compressor is coupled or uncoupled only when at rest and for this purpose the pin will be found satisfactory, but other means are within the contemplation of our invention.

In order that the appliance may be connected and disconnected at will, we preferably provide a short extension shaft 14 having a splined end 15 lying adjacent the end of the motor shaft 12. The precise shape of the end of the shaft 14 will of course be determined by the type of connection used between the shaft 14 and the motor 11.

In Figure 5 we have illustrated a modified form of attachment member 4 bolted to a. frame 5 by means of bolts 6. The at tachment member 4 is provided with an extension portion 1G having flanges 17 and 1S at the ends thereof. rIhe fiange'l? abuts the end of the frame 5', while the flange 18 is adapted to engagethe appliance which may be bolted to the attachment member. As in the previously described embodiment, the attachment member 4 is provided with a threaded end. portion 9 by which'the appliance may be securely attached thereto. The extension portion 16 serves to space the appliance from the automotive vehicle to provide ample clearance for any type of flexible connection or clutch which may be employed between the appliance and the motor. ItV further insures ample clearance for any external fan which may be used to aid in cooling the motor 11. The attachment members 4 and 4 are preferably made relatively long and havev an extended area of contact with the frame of the vehicle. The provision of an eX tended contact between the attachment members and the frame insures a rigid connection and avoids concentrating the load on a small portion of the frame. Furthermore, ample space is provided for inserting bolts, through the attachment member and the web and fianges of the frame, withoutweakening the joint.

As hereinbefore stated this invention is not limited to a connection for an air compressor, but contemplates an improved means for operatively attaching any portable power operated appliance to an automotive vehicle.

The advantages of the present invention arise from the provision of a simple and effective means for rigidly securing a power operated appliance to the frame of an automotive vehicle. Further advantages accrue by reason of the provision of rigid attaching means from which the appliance may be quickly disconnected.

Ve further provide attaching means whereby a power operated appliance may be quicklyv and rigidly attached to the frame of an automotive vehicle and operatively connected with the engine of such vehicle.

lhile we have illustrated and described the present preferred embodiment of our invention, it will be understood that the invention is not limited thereto but may be otherwise embodied within the scope of the following claims.

We claim:

1. The combination of an automotive vehicle having an engine shaft and channeled frame members, a pair of bars fitting between vertically-spaced fianges of said frame members, means to prevent spreading of said flanges, a compressor supported solely by said bars close to the front of the vehicle, and means for driving the compressor from said engine shaft.

2. The combination of an automotive ve hicle having an engine shaft and channeled frame members, a pair of bars fitting between vertically-spaced flanges of said frame members, bolts passing vertically through said flanges and bars to prevent spreading of the flanges, a compressor supported solely by said bars close to the front of the vehicle, and means for driving the compressor from said engine shaft. Y

3. The combination of an automotive vehi cle having an engine shaft and channeled frame members, with means for supporting a sprung weight comprising a pair of bars having relatively long parts fitting between vertically-spaced fianges of said members and relatively short studs projecting beyond said frame members, integral collars on the bars back of said studs resting against the front ends of said frame members, a loadsupporting plate. with holes to receive said studs, and means on said studs for holding the plate in place againstsaid collars.
